1. Elevator contour (check)
2. Canard incidence (check)
3. Any recent addition of wheelpants?
Don't go playing around with W&B or revised trim springs until you verify 1 and 2 above. Note also that the aft CG limit for the Long-EZ was changed from FS 104 to FS 103 in Canard Pusher (CP) 39 (Long-EZ Plans Change (LPC) #116).
Addition of wheelpants will (or will have a high-probability to) change the pitch trim characteristics - it is possible to run out of forward trim at higher airspeeds if wheelpants are introduced onto the airplane where they previously were never installed.
